Dispensing device with control body in order to axially move a dispensing element

ABSTRACT

1. Dispensing device. 
     2. A dispensing device having a container, the receiving space of which contains a dispensable medium, which can be extracted by means of a dispensing element of the device for an extraction process, and having a control body ( 19 ), which, by means of a rotary movement, moves a connecting body ( 11 ), which is guided in a housing part ( 9 ) such that it can be displaced longitudinally, from an inactive initial position into an active extraction position, wherein a media-carrying connection is established between the receiving space and the dispensing element, wherein at least one control part of the control body ( 19 ) can be brought into abutment with at least one control path ( 54 ) of the connecting body ( 11 ), characterized in that the respective control part ( 57 ), viewed relative to the housing part ( 9 ), follows the rotary movement in an axially unchanged manner when the control body ( 19 ) is rotated, and moves the latter from the initial position into the extraction position via the respective allocatable control paths ( 54 ) of the connecting body ( 11 ), the former having a slope.

The invention relates to a dispensing device, the receiving space ofwhich contains a dispensable medium, which can be extracted by means ofa dispensing element of the device for an extraction process, and havinga control body, which moves a connecting body, guided in alongitudinally displaceable manner in a housing part, from an inactiveinitial position to an active extraction position, by means of a rotarymotion, wherein a media-carrying connection is created between thereceiving space and the dispensing element, wherein at least one controlpart of the control body can be brought into abutment with at least onecontrol path of the connecting body.

Dispensing devices of this type are used for technical, cosmetic,pharmaceutical and medical purposes, in particular in conjunction withinjections as a means for administering medication. The dispensingdevices are intended to allow the operator to safely and convenientlyperform the measures to be taken for the application of the containermedia, allowing, for instance in the case of disposable syringes, thedelivery device to be used by the patient himself. As prior art, WO2012/113008 discloses a dispensing device of the type initially referredto, in the form of a syringe head for an injection syringe, wherein aprotective cover for the injection needle forming the dispensing orificeis provided as a control body to be operated for an extraction process.By means of a rotary movement of the protective cover, a connecting bodybearing the injection needle is axially movable in a housing part, whichcan be coupled to an injection cylinder in such a way that theconnecting body establishes a media connection with the container, herethe interior of the injection cylinder. In order to convert the rotarymovement of the protective cover into the axial movement of theconnecting body, in the known solution a drive part, which is connectedin rotation to the protective cover and is referred to in the documentas a “pinion”, has circumferential, radially projecting guide knobs,which are arranged in the housing part that is mounted on the container,in this case on the injection cylinder. Depending on the inclination ofthe slotted-guide tracks, the rotational movement transmitted by couplerlamellae from the protective cover to the pinion causes the longitudinaldisplacement of the pinion and through this the opening movement of theconnecting body.

The known solution is unsatisfactory in several respects. On the onehand, the design of the coupling connection between the protective coverand the pinion entails a corresponding structural complexity. On theother hand, the reliability of the function leaves a lot to be desired,as, for the typically used polymer materials with limited stiffness, theentry of the guide knob into the slotted-guide tracks and the guidanceinside the latter are not proof against jamming.

In addition, the pinion has to fit tightly over the cannula duringmanufacture, which can easily result in damage to the needle tip and/orthe silicone layer on the needle. This can directly affect the user, assuch damage can easily lead to painful injections.

Based on this state of the art, the invention addresses the problem ofproviding a dispensing device of the type mentioned at the outset, whichis characterized by an improved functional reliability in a simpledesign.

According to the invention, this problem is solved by a dispensingdevice having the features of claim 1 in its entirety.

According to the characterizing part of claim 1, an essential feature ofthe invention is that during the rotary movement of the control body,the respective control part follows the rotary movement relative to thehousing part in an axially unchanged manner and, via the respectivecontrol path of the connecting body, which has a slope, moves the formerfrom the initial position to the extraction position. Because thearrangement is such that the control part does not execute an axialmovement during the rotary actuation, no clutch device is required topermit an axial movement between the control element and the controlpart upon transmission of the actuating torque. The device according tothe invention can be realized in a particularly fail-safe manner using asimplified design based on conventional plastic materials, such aspolyolefins.

In particularly advantageous exemplary embodiments, the control body hastwo control parts which are diametrically opposite in relation to thelongitudinal axis of the device, which are, in the initial position ofthe connecting body, rotatable from a lower vertex position formed bythe respective control paths of the connecting body in the direction ofan upper vertex position of the respective control paths, which arearranged above the lower vertex position in the initial position of theconnecting body in axial direction, relative to the longitudinal axis.Unlike WO 2012/113008, in which the axial displacement of the connectingbody tightly enclosing the cannula is transmitted to the connecting bodyvia an axially movable pinion, the connecting body can be directlyactuated via the axially immobile control parts of the control body,which are supported by the control paths of the connecting body andwhich upon rotary movement move away from the lower vertex position ofthe guide paths and thereby effect the axial displacement of theconnecting body in a particularly secure manner.

In a particularly advantageous manner, the respective control path canencompass, at least partially, in a hollow ring-like and co-axialmanner, a connecting channel, which is located in the connecting bodyand constitutes the media connection to the container, wherein afunctional body specifically designed for the particular containerapplication is arranged on the connecting body. In this case, thefunctional body can, for instance in the case of an injection, have acannula, in the case of a transfer into another receptacle, the closureof which has to be punctured, have a hollow mandrel, in the case of adropper application, have a dropper, in the case of ointment or gelapplication, have an ointment applicator, in the case of an as yetunknown application, have a connecting element, for example a conicalconnection.

Functional bodies and connecting bodies can be separate components,which may, for instance, be interlockable. This has the advantage ofusing similar connecting bodies for different functional bodies.Alternatively, connecting bodies and functional bodies can also beintegral with each other, i.e. no sealing is required between theconnecting channel and the functional body.

The control body can be designed in the manner of a protective cover forthe respective functional bodies, supporting on its inside the controlpart in the form of at least one inwardly projecting lug part, which isformed at least partly convex in the direction of the connecting bodywhen the protective cover is on.

For particularly advantageous exemplary embodiments, the protectivecover can, in the direction of its open free end having at least oneprotruding annular segment, reach under an assignable annular segment ofthe housing part in the inactive initial position of the protectivecover at this housing part, such that after a rotation of the protectivecover around a predetermined distance, until the connecting body hasreached its active extraction position, the paired annular segments,which are disengaged from one another, and the protective cover, can beremoved from the housing part. Whereas, in the case of theaforementioned WO 2012/113008, in which the protective cover is merelysecured by way of a predetermined breaking point on the housing part,there is the risk of the operator removing the protective cover afterpartial rotational actuation by detachment of the predetermined breakingpoint and thus no effective extraction process can be carried out; thisrisk is eliminated in the invention because the protective cover canonly be removed when the active extraction position has been reached.

With particular advantage, the connecting body is provided with at leastone longitudinal guide, guided longitudinally movably in the housingpart and secured against all rotational movement.

Depending on the application purpose of the device, the respectivecontainers can be molded to the housing part and/or subsequently beconnected to the housing part as an independent component. In aparticularly advantageous manner, for a dispensing device allocated to acontainer, which is produced in a blow-molding process, such as theknown bottelpack® process and filled in the mold, the container can beconnected to the housing part in the blow mold.

The subject matter of the invention is also a carrier unit for afunctional body which is provided, in particular, for a dispensingdevice according to one of claims 1 to 9 and which has the features ofclaim 10 in its entirety.

As a further subject matter the invention provides a container systemhaving the features of claim 11 and consisting of an outer closedsheath, the sheath parts of which can be separated from each other alongat least one separation point, to expose a dispensing device, which isdesigned in particular according to one of claims 1 to 9, or a carrierunit, which is designed in particular according to claim 10.

With reference to the drawings, the invention is explained by means ofexamples, in which the dispensing device for the extraction of liquid orsemi-solid filling material from a plastic container is provided, as itcan, in the manner of an ampoule, for instance, according to thebottelpack® method, be manufactured and filled in a blow mold. FIGS. 1and 2 show, in a separate view, a corresponding container 1 having acontainer body 3, which is designed and compressible in the manner of aflat bellows, so that it can be used for carrying out an applicationprocess, e.g. an injection process. The container 1 in the illustratedexamples designed for a filling volume of 1 to 2 ml transitions from thecontainer body 3 via a collar part 5 into a neck part 7. If such acontainer 1 is provided for use in connection with an extraction deviceaccording to the invention, the extraction device is attached to theneck part 7 by a housing part 9, see FIG. 3.

FIG. 4 shows the components of a first exemplary embodiment of theextraction device according to the invention having a connecting body 11guided such that it can move longitudinally in the housing part 9. Ithas an inner, axial connection channel 13 for a fluid-conductingconnection to the contents of the container 1 during the extractionprocess. A functional body 15 adjoins the upper, in FIG. 4, end of theconnecting body 11, which continues the inner channel 13 of theconnecting body 11 to a functional part forming the dispensing element,in the present example, an injection needle 17. The upper termination ofthe device is formed by a protective cover 19, which in the mountedposition, see FIGS. 5, 7 and 8, reaches over the functional body 15 andthe connecting body 11, and the open rim region of which is locked tothe housing part 9, as will be explained in more detail below. Theprotective cover 19 forms a control body, which can be used to transferthe device from the initial position into an active extraction position.This happens by means of a rotary movement of the protective cover 19,which is provided with an external longitudinal corrugation 21 for goodtraction.

Further details of the construction of the housing part 9 and theconnecting body 11 can be seen most clearly in FIGS. 9 to 12. Thehousing part 9 has, on the whole, the shape of a hollow cylinder havinga coaxial inner cavity 25, which is closed at the end 27 located at thebottom in FIGS. 11 and 12. If the extraction device, as in the case ofthe present exemplary embodiment, is provided for the extraction offilling material from a container 1, which is produced in a blow moldingprocess and is filled in the mold, the complete assembly shown in FIG. 5can be inserted into the former as an insert before the final closure ofthe blow mold. When the head jaws of the mold are closed, the plastichose forming the neck part 7 of the container 1 is then molded to theoutside of the housing part 9, as can be seen in FIG. 13. The closed end27 of the housing part 9 thus forms the container closure. Acircumferential ribbing 23 on the housing part 9, which is shown as alongitudinal ribbing in FIG. 4 and a horizontal ribbing in FIGS. 11 and12, forms a kind of gearing for a fixation based on a positive-lockingengagement during the shaping of the neck part 7.

From the closed end 27, a truncated cone 29, open at the end, extendscoaxially into the cavity 25. Close to its opening, the truncated cone29 is closed by a membrane 31, forming the perforation region, which ispierced in the extraction process, see FIGS. 7 and 8, by a hollowmandrel 33 which, as shown most clearly in FIG. 10, forms the lower endof the connecting channel 13 in the connecting body 11. The connectingbody 11 is displaceable in the cavity 25 of the housing part 9 formoving it from the initial position (FIG. 7) into the extractionposition (FIG. 8), in which the mandrel 33 has pierced the membrane 31,longitudinal ribs 35 on the housing part 9 forming a longitudinal guidein conjunction with longitudinal grooves 37 in the cylinder jacket 39 ofthe connecting body 11. For an engagement of the connecting part 11 inthe initial position and in the axial positions corresponding to theextraction position, upper latching notches 41 and lower latchingnotches 43 are formed at respectively diametrically opposed locations onthe cylinder jacket 39 of the connecting body 11, for engagement withlatching lugs 45 on the inside of the cavity 25 of the housing part 9 inthe initial position or in the extraction position.

As mentioned before, the protective cover 19 is locked on the housingpart 9 at the rotational position corresponding to the initial position.For this purpose, it has annular segments 47 at the open end, betweenwhich gaps 49 are located. As complementary locking elements, projectingannular segments 51 are formed at the open end of the protective cover19, which reach under the annular segments 47 on the housing part 9 atthe rotational position corresponding to the initial position, as shownin FIG. 5. When the protective cover 19 is rotated into the rotationalposition corresponding to the extraction position, annular segments 51in the region of the gaps 49 are removed from the engagement with theannular segments 47 and the protective cover 19 can be removed. In thatway, a bayonet-type interlock is formed.

As can best seen in FIGS. 9 and 10, the connecting body 11 has aradially protruding flange part 52 at the upper end of its cylinderjacket 39, the wall parts 53 of which, forming parts of a circularcylinder, extend coaxially. The free upper rim of the wall parts 53forms control paths 54, which extend between the lower vertex position55 and the upper vertex position 56. To generate the longitudinaldisplacement of the connecting body 11 from the initial position intothe extraction position, the protective cover 19 has two control parts,which are diametrically opposite in relation to the longitudinal axis ofthe device. As can best be seen in FIGS. 5 and 6, they have the shape oflugs that are rounded at their ends 57, which are arranged in theinterior of the protective cover 19 at the transition to a radiallyexpanded cylinder section 58 of the protective cover 19, the formerbeing arranged on the outside of the wall parts 53 of the connectingbody 11. FIGS. 5 and 7 show the rotational position of the initialposition, in which the ends of the lugs 57 are located at the lowervertex position 55 of the control paths 54. If the protective covers 19are rotated by 90° in one or the other direction of rotation, the lugs57 move towards the upper vertex position 56 of the control paths 54,generating the axial displacement of the connecting body 11 and thus themovement of the mandrel 33 piercing through the membrane 31, atunchanged axial positions of the protective cover 19 and the housingpart 9. For a pierced membrane 31 (FIG. 8), the part of the connectingbody 11 surrounding the channel 13 and forming the mandrel 33, extendsinto the truncated cone 29 with an end cone 63, the end rim 65 of whichis in contact with the end cone 63 as a sealing lip. If the protectivecover 19 reaches the position rotated by 90° and if the extractionposition is reached, the annular segments 51 of the protective cover 19come into alignment with the gaps 49 on the housing part 9 and then theprotective cover 19 can be removed, and the injection needle 17 isreleased for an application procedure.

As can be seen most clearly in FIG. 4, the functional body 15 as carrierof the injection needle has a initial body 59 which, as can be seen mostclearly from FIGS. 7 and 8, reaches over a pin part 60, which at theconnecting body 11 surrounds the end section of the connecting channel13. The fluid connection from the connecting channel 13 to the needle 17continues in the interior of the initial body 59. The functional body 15has, for attachment to the connecting body 11, radially projectingflange parts 64 from the lower edge region, which in the installed stateadjoin the planar upper side 62 of the flange parts 52 of the connectingbody 11 and are held thereon by wall parts 61, which are formed oncutouts of the wall parts 53 of the connecting body 11. By means of thefunctional body 15 thus fixed to the extraction device, the protectivecover 19 can be removed in the extraction position, and an extractionprocess can be carried out by executing an application of fillingmaterial by means of the injection needle 17 by compressing thebellows-like container body 3 of the container 1. The same applies tothe application of drops, e.g. for oral, nasal, ophthalmic, topical,etc. treatments, as well as the application of semi-solid products suchas ointments, creams or gels, using suitable, applicators known per se.

FIGS. 13 to 15 show a modified exemplary embodiment in which theprotective cover 19 is enclosed by an outer sheath 71. This can beformed during the production of the container 1 by blow molding from theplastic hose adjoining the neck part 7, which is extruded into the blowmold, when the mold head jaws are closed, wherein a predeterminedbreaking point 66 (FIG. 13) can be formed at the place of attachment tothe neck part 7, where the sheath 71 can be detached together with theprotective cover 19. As a further difference to the previous exemplaryembodiment, the connecting body 11 does not have a mandrel 33 made ofplastic molded onto the main body 59, but a hollow needle 67, which isshown in the initial position in FIG. 13 and in the extraction positionafter piercing the membrane 31 in FIG. 15. In this embodiment, the partof the connecting body 11 is eliminated, which in the previouslydescribed exemplary embodiment forms the end cone 63 having theadjoining mandrel 33 at the end of the connecting channel 13, as thehollow needle 67 itself forms the seal on the pierced membrane 31.

In a preferred case (not shown), the needle 17 and the hollow needle 67may be formed integrally, as a double-pointed injection needle,resulting in a small, unusable dead volume.

FIG. 16 shows an exemplary embodiment in which, as in the example ofFIGS. 13 to 15, a hollow needle 67 is provided on the base body 59 ofthe functional body 15 instead of a plastic mandrel 33 molded to theconnecting part 11. In the example of FIG. 16, however, the container 1is not molded with its neck part 7 to the outside of the housing part 9.On the contrary, the container 1 has a closed neck part 7, to which thehousing part 9 is tightly connected, e.g. glued, locked or welded. Asshown in FIG. 16, a sealing layer 69 made of an elastomer rests on theplanar upper end wall 68. In the extraction position, the hollow needle67 penetrates the elastomer material and the wall 68 of the neck part 7.

The further exemplary embodiment shown in FIGS. 17 and 18 differs fromthe example of FIG. 16 only in that the housing part 9 has a sleeve-likeextension 70, which is used to snap the housing part 9 onto the outsideof the neck part 7 of the container 1. Again, the neck part 7 is closedby a planar wall 68, to which a sealing layer 69 of elastomer isattached. FIG. 18 shows the extraction state having a pierced sealinglayer 69 and pierced wall 68.

In the further exemplary embodiment of FIGS. 19 to 21, the neck part 7of the container 1 is again molded onto the outer side of the housingpart 9, as in the examples of FIGS. 1 to 15. Also, a plastic mandrel 33is formed onto the connecting body 11 for piercing the diaphragm 31 ofthe housing part 9. Instead of an injection needle 17 forming thedispensing element, a hollow application pin 72 is mounted to the basebody 59 of the functional body 15. By means of such a mandrel 72, forinstance, an elastomer closure of an injection bottle or an infusion bagcan be pierced. As a further difference to the first-describedembodiment of the housing part 9 in the example of FIGS. 19 to 21, thelatter has a hollow end cone 73 extending along the inside of the collarpart 5 into the inside of the container body 3 at the end facing thecontainer 1. Furthermore, as in the example of FIGS. 13 to 15, an outersheath 71 surrounding the protective cover 19 is detachably molded overa predetermined breaking point 66.

The further modified exemplary embodiment of FIGS. 22 to 24 correspondsto the exemplary embodiment of FIGS. 19 to 21, with the difference thatno functional body 15 continuing the connection channel 13 is attachedto the connecting body 11. Rather, the end-side pin part 60 of theconnecting body 11 is designed as a connection part, for instance in theform of a conical connection 74 or for the formation of an interlockableconical connection part. As provided in the examples of FIGS. 13 and 19,an outer sheath 71 is provided for the protective cover 19, the formercan be removed together with the protective cover 19 after thepredetermined breaking point 66 has been released. Particularlyadvantageous is a substance-to-substance, positive-locking and/orform-locked connection of protective cover 19 and outer sheath 71.

FIGS. 25 to 28 show an exemplary embodiment in which the dispensingdevice forms a completely encapsulated container system. In this regard,several casing parts are provided, which extend from the container body3 of the container 1 to the upper end 76 allocated to the dispensingelement. In this case, a first casing part 77 is provided, whichconjunctively surrounds, starting at the upper end 76, the innerprotective cover 19 with a central part 78 having the form of anexternally concave, curved tubular body and which has laterallyprojecting wing parts 79 arranged diametrically opposite to each otheras handle parts. The wing parts 79 have a convexly curved end rim 80.This casing part 77 is detachably connected to a second casing part 82,which surrounds the housing part 9, via a predetermined break point 81.Wing-shaped grip flaps 83, which are aligned with the wing parts 79 ofthe first casing part 77, extend diametrically outwards from the secondcasing part 82. Stay bars 84 extend from the grip straps 83 to theoutside of the container body 3.

The casing part 77 is connected to the outer longitudinal corrugation 21of the protective cover 19. In this way, by releasing the predeterminedbreaking point by rotating into any direction of rotation, the rotarymovement of the protective cover 19 is simultaneously initiated to movethe device into the extraction position, where the protective cover 19can be removed. The first casing part 77 can be conveniently separatedby means of the wing parts 79 serving as handles. When the device is inthe extraction position, i.e. after removal of the casing part 77together with the protective cover 19, the device can be convenientlyhandled for the respective intended application processes by means ofthe lateral grip straps 83 remaining in connection with the containerbody 3. In the case of the bracing formed by the bars 84, the functionalbody 15 can be safely used, for instance, for injection purposes,without the premature compression of the container body 3 occurring,because the actuating force for activating the dispensing device is notapplied via the container 3 but via the grip straps 83.

The internal structure of the device, not shown in FIGS. 25 to 27, canessentially correspond to the exemplary embodiment described first, asillustrated by way of example in FIG. 28. It goes without saying thatvariations of averted device parts can be present within theencapsulation formed by the cover parts 77, 82, which, for instance,correspond to the exemplary embodiments according to FIGS. 13 to 24.
